WASHING MACHINE.

Application filed November 217 1922. Serial No. 602,355.

T0V all whom t may concer/1t Be it known that I, Hosirnn BLUM, a citizenof the United States, residing-at the city and county of San Francisco,and State of California, have invented certain new and usefulImprovements in Vashing Machines, of which the following isaspecification.

The prevailing types of washing machines now in use either includeseparate tubs or trays within which the washing mechanism operates andwhich are separate from the permanent trays installed within a dwellingor are of the type adapted to be attached or secured to a buildingstructure or to the wall of a permanent tray. Both of theseconstructions require considerable expense in their constructionand'installation.

The present -invention relates to a washing machine designed forpositioning ywithin a permanent tray containing articles to be washedand which is supported by and rests on the articles.

This invention has for its objects to provide a multi-cupped structurewhich is free to move during its operation over the area of the articlescontained within the tray, and during such movement to' cause by itsoperation a water circulation through the articles, which circulation iscaused by the action of the cupped structures. Another object is toprovide a multi-cupped mechanism wherein the cups are mounted forrelative reciprocation and alternately support the weight'of theoperating mechanism.

lilith the above mentioned and other objects in view, the inventionconsists in the novel construction and combination of parts hereinafterdescribed, illustrated in the accompanying drawings, and set forth inthe claims hereto appended, it being understood that various changes inthe form, proportion, size and minor details of construction within thescope of the claims may be resorted to without departing from the spiritor sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference is directed to theaccompanying drawings, wherein Fig. 1 is a vertical sectional view ofone embodiment of my invention positioned within a tray containingarticles to be washed.

Fig. 2 is a transverse sectional view of the washing machine.

Referring more particularly to the Several views of the drawings whereinlike characters of reference designate correspondingparts, 1 indicates aconventional trayand in the bottom thereof is positioned a grating orother member 2 affording a sump or water vcirculating space 3 below thesame. The tub or t-ray is adapte-d to contain water at within which areplaced the articles 5 to be washed.

Through the upper opent'op 6 of the tub or tray is positioned thepreferred embodiment of my invention, which includes a cylindrical opentop chamber 7 mounted with hand grips 8 to facilitate the lifting andtransporting thereof and the open top of which is closed by a cover 9,the flange 10 of which preferably is received within the upper end ofthe chamber, and the supporting flange 11 of which directs moisture eX-teriorly of the chamber. The chamber 7 rests on a member 11', the sidewall of which is downwardly flanged as at 12 forming an outer cuppedmember 13. The member 11 is provided with the vertically disposed guidesleeves 14 within which are mounted to reciprocate guides or stems 15mounting on their lower ends the cupped or bell shaped member 17. Thismember 17 is formed in its center with a guide opening 18, and into saidopening extends the guide tube 19 depending centrally from the underside of the member 11. It will be observed that the member 17 isdisposed concentricvally within the outer cupped member 13, and

is guided in its reciprocating movement by the members 14C and 19. Across head 20 connects the upper ends of the stems 15, and said head islongitudinally slotted as at 21 to receive a crank pin 22, extendingfrom the spider of a gear 23 rotatable on the spindle 24 carried by abracket 25 sccured to the side wall of the chamber 7. The bracket alsomounts a motor 26, the shaft 27 of which carries a pinion 2S whichintel-meshes with the gear 23. The motor is supplied with currentthrough a conductor 29 which extends eXteriorly of the apparatuspreferably through an opening 30 in the cover 9.

The apparatus being connected to a source of electricity and positionedwithin a tub or tray containing wash wat-er and the articles to bewashed, the apparatus operates in the following manner y It will beobserved that the weight of 'the entire apparatus is supported by thearticles the cupped members is repeated and causes the movement of theapparatus over the entire area of the tub, thus the apparatus isprevented from remaining iny a single position and in its operationtravels over the articles to be washed.

their not in use, the apparatus which is Acomparatively small, cairremain in' the tub or trayl after the articles to bewashed have been.removed' therefromy and. the water drainedl fromthc tray, thus theapparatus does not require a separate storage space when not in use;grating 2 at the base' of the tra-y prevents the packing-of the articlesto bey washed in the bottom of the tray and enables a water circulationtlrrough the articles to bel washed to be maintained.

The relative telescoping movement of the eulps` lQ'and 17 creates apowerful alternatel s-uctren and compressionaction on= the washl watercausing a circulation of the samein alternate directions through thearticles to beY washed.

Having thus described my invention, what claim` and desire to protect byLetters-` Patent of the' United- States is :-v

l. A Washing' machine including a chambercd' member havingan openbottomed cupped' member at its lower end, a second cupped memberdisposed' concentrically wit-hin f the li'rstv cupped member, meansextending 'intol th-e Chamber and connected with The employment of thelthe second cupped member, an electric motor fixed within. the chamber,and a geared driving connection between the motor and the meansextending into the chamber' for simultaneously operating said cuppedmembers toward and from each other.

2. A washing machine including a bell bottomed' chamber, a bell bottomedmember concentrically disposed within the bottom of said chamber `forreciprocating movement into and-out of the same, an electric motor fixedwithin the receptacle, and a geared driving connection between the motorand the second bell bottomed chamber wherebyrelativel reciprocatingmovement is simultaneously imparted to said bell bottomed members.

31. A'washing'machine including a casing having a cupped Vbottom member,guides eX- tendiirg upwardly th-rough said dividing wall into saidcasing, a second cupped member concentrically disposed within the cuppedbottom member of the casing and Carried by said guides, al motor fixedwithin thecas` in1g,a cross-head connecting the1 guides, gear mechanismwithin theA casing and connectingfthe crosshead and motor for impartinga relativereciprocating movement to said cupped members, saidsecondcupped member adapted forA reception within said cupped bottom.

t. A washing' machine including a casing having a cuppedbottom member, asecond cupped member concentrically within thecupped bottom member 4ofthe casing, operating means extendingv upwardly from said second cuppedmember, an electric motor withintlre casing and carried thereby, ageared driving connection beftween the motor and the operating meanswhereby 'onthe operation of the motor movement is imparted tosaid'cupped members.

In testimony whereof have signed my name` to this specification'.
